A111 Overview
The A111 is a radar system based on pulsed
coherent radar (PCR) technology and is setting a
new benchmark for power consumption and
distance accuracy – fully integrated in a small
package of 29 mm
2
.
The A111 60 GHz radar system is optimized for
high precision and ultra-low power, delivered as a
one package solution with integrated Baseband,
RF front-end and Antenna in Package (AiP). This
will enable easy integration into any portable
battery driven device.
The A111 is based on leading-edge patented
sensor technology with pico-second time
resolution, capable of measuring absolute
distance with mm accuracy up to a range of
2 m
(1)
and with a continuous sweep update
frequency fully configurable up to 1500 Hz
(2)
.
The A111 60 GHz radar remains uncompromised
by any natural source of interference, such as
noise, dust, color and direct or indirect light.
Applications
•
High precision distance measurements with
mm accuracy and high update frequency
•
Proximity detection with high accuracy and
the possibility to define multiple proximity
zones
•
Motion detection, Speed detection
•
Enables material detection
•
High precision object tracking, enabling
gesture control
•
High precision tracking of 3D objects
•
Monitor vital life signs such as breathing and
pulse rate
